DETAILED DESCRIPTION

The digital license plate system 11 is preferably used for registeredvehicles such as personal cars, trucks, motorcycles, rental cars,corporately-owned cars, or any other suitable type of vehicle. Thedisplay system 100 functions to render identification, insurance status,expiration date, registration, or other information of the vehicle 10that is preferably provided by an official authority, such as aDepartment of Motor Vehicles (DMV). Preferably, the processor 120renders the identification and/or registration information of thevehicle 10 on the display 110 such that a state vehicle code isfollowed, such as the size and dimension of the displayed area, thecontent, size, and lettering style of the information, and thevisibility and reflectivity of the display 110. Preferably, theprocessor 120 renders content on the display 110 such that the statevehicle code of the state in which the vehicle 10 is registered isfollowed; alternatively, such as in the embodiment of the invention thatincorporates a location sensor (such as a GNSS receiver), the processor120 may render content on the display 110 such that the state vehiclecode of the state in which the vehicle is located is followed. Thedisplay system 100 preferably functions to display a message in additionto the vehicle identification and/or registration information. Themessage is preferably provided by an advertiser, for example, anadvertiser that is substantially unrelated to the user. The subjectmatter of the advertisement provided by the advertiser may besubstantially unrelated to the driver and/or owner of the vehicle 10,and the advertisement may be substantially unrelated to the vehicle 10.Alternatively, the advertisement may be related to a demographic towhich the driver and/or owner of the vehicle 10 belongs or to any othersuitable characteristic of the driver and/or owner of the vehicle 10.The advertisement may also be selectable by the driver and/or owner ofthe vehicle 10, for example, via the Internet on a personal computer,via the internet on an internet-capable mobile phone, or via any othersuitable method. The advertisement may also be substantially related tothe vehicle 10, for example, a display system mounted to a Porsche maydisplay advertisements that are targeted at a demographic with a brandaffinity toward Porsches. The advertisements may be substantiallyrelated to the location of the vehicle 10, for example, if the vehicle10 is traveling within the vicinity of a venue, an advertisement for thevenue may be shown. Alternatively, the message may be provided by a lawenforcement agency, for example, an emergency broadcast regarding amissing person (for example, an Amber or an Elder alert). Furthermore,if the vehicle 10 is reported stolen, the message may indicate that thevehicle 10 is stolen, thus allowing parties external to the vehicle toidentify the vehicle 10 as such.

Alternatively, the message may be any suitable type of message and maybe controlled by any suitable party, for example, an officialorganization (for example, the DMV), the driver of the vehicle 10, theowner of the vehicle 10, a third party unrelated to the vehicle 10, orany other suitable party. In a first example, the message may includeadditional details related to the vehicle 10, including the model of thevehicle 10, the smog check results of the vehicle 10, maintenance issuesof vehicle 10, or any other suitable type of information related to thevehicle 10. In a second example, the message may include details relatedto the driver of the vehicle 10, including organizations that the driversupports or belongs to (for example, the Girl Scouts, the San FranciscoGiants baseball team, or a political party), a cause that the driversupports (for example, People for the Ethical Treatment of Animals(PETA) or cancer awareness), the demographic of the driver, or any othersuitable type of information related to the driver. In this secondexample, the message may also include official details regarding thedriver; for example, the message may indicate that the driver is adoctor or a law enforcement officer, allowing people outside the vehicle10 to direct requests to the driver when his services are desired.Official details may also include details relating to the drivinghistory of the driver; for example, if the driver has an imperfectdriving record, a notification may be rendered on the display in orderto warn others in the vicinity of the vehicle. In a third example, themessage may include notifications for drivers in the vicinity of thevehicle 10, for example, traffic information or weather forecasts. In afourth example, the message may include details regarding the owner ofthe vehicle. This may be particularly useful when the vehicle 10 is amember of a fleet of cars, for example, a car rental agency, a movingtruck rental agency, a government fleet, or any other suitable type offleet. The message of the fourth example may indicate which fleet thevehicle 10 belongs to; this information may be used to identifyvehicles, to advertise regarding the fleet (for example, if the vehicle10 belongs to a rental car agency, the message may include anadvertisement or a message for that particular rental car agency), orfor any other suitable purpose. However, the message may be of any othersuitable type of message.

The display system 100 is preferably powered by a power source. Thepower source is preferably a power source of the vehicle 10, such as theaccessories battery of the vehicle 10, the engine of the vehicle 10, orany other suitable power source of the vehicle 10. Alternatively, thedisplay system 100 may include and be powered by a power source that issubstantially independent from a power source of the vehicle 10. Thepower source of the display system 100 is preferably a battery, but mayalternatively be a solar panel, wind generator, or any other suitabletype of power source or combination of power sources. Yet alternatively,the display system 100 may include a power source that is rechargeableand coupled to a power source of the vehicle 10 that stores power fromthe vehicle 10 while the vehicle 10 is in operation and/or the ignitionof the vehicle 10 is on. In this variation, the power source of thedisplay system 100 allows for power generated while the vehicle is inoperation to be used at a later time by the display system 100. However,the display system 100 may be powered using any other suitable methodand/or arrangement.

The display 110 functions to display content, wherein content includesat least one of the identification information of the vehicle 10,registration information of the vehicle 10, and a message. The display110 is operated by the processor 130 in one of the three operationalmodes. The display 110 is preferably of a substantially low powerdisplay, such as an LED display, an LCD display, an e-ink display, anorganic LED display, an interferometric modulator display (iMoD), adisplay that uses electrophoretic deposition (EPD), a cholesteric liquidcrystal display (ChLCDs), or any other suitable display. The display 110may alternatively be a combination of the above display types. Thedisplay 110 preferably also has a substantially wide range of viewingangles. The display 110 is preferably also substantially thin, allowingthe display 110 to replace existing license plates on the rear and/orfront exterior of the vehicle. Similarly, the display 110 is preferablyof a width, height, and/or aspect ratio that is/are substantiallysimilar to existing license plates. Alternatively, the display 110 maybe substantially different than existing license plates (for example, inthe case of the relatively narrow height of European license plates, thedisplay 110 may be of a substantially different height). However thedisplay 110 may be of any other suitable dimension.

The display 110 may also include a backlight. The backlight functions tocontrol the light intensity of the information displayed by the display110. The backlight preferably includes a plurality of degrees of lightintensity. The processor 130 may select the degree of light intensitybased upon the mode of operation. The processor 130 may also select thedegree of light intensity based upon ambient light levels proximal tothe display 110. For example, the degree of light intensity may behigher during the day and lower during the night. In this variation, thedisplay system 100 also includes a light sensor to detect the level ofambient light. The degree of light intensity of the display system 100may also be selected based on the preferences of the driver, a lawenforcement officer, or any other suitable party. However, the degree oflight intensity of the display system 100 may be selected based on anyother suitable criteria. The backlight may be a set of lights locatedsubstantially on the perimeter of the display 110 and that are directedtoward the display 110. Alternatively, the backlight may be locatedsubstantially behind the display 110 and provide light from behind thedisplay 110. However, the backlight may be of any other suitablearrangement. The backlight may be a series of low-power light sources,such as LEDs, but may alternatively be any other type of light source.Alternatively, the display may include a light-reflective surface thatfunctions to illuminate the display 110 with reflected light. Thelight-reflective surface may be a mirror or any other suitable type ofreflective material. The light-reflective surface may also be of aretroreflective material that reflects light back in the direction ofthe light source. The light-reflective surface may also be combined witha light source to more effectively illuminate the display 110, forexample, the transflective materials used on freeway signs. However, anyother suitable material or method may be used to illuminate the display.

The vehicle speed sensor 120 functions to detect the speed of thevehicle 10. The vehicle speed sensor 120 is preferably a sensor thatmeasures the actual velocity and/or acceleration of the vehicle 10, suchas an accelerometer coupled to the vehicle 10 or a tachometer coupled tothe drivetrain of the vehicle 10 and which measures the number ofrevolutions of a drivetrain component, such as a wheel, for a period oftime in order to determine the speed of the vehicle 10. In a secondvariation, the vehicle speed sensor 120 couples to the speedometer ofthe vehicle 10 and/or an onboard computer of the vehicle 10; in thisconfiguration, the speed sensor 120 functions to transmit informationgathered by the speedometer and/or the onboard computer to the processor130, rather than measure the vehicle speed directly. However, thevehicle speed sensor 120 may be any other suitable type of sensor thatdetermines the actual speed and/or acceleration of the vehicle 10,including but not limited to a GNSS receiver or inertial navigationsystem. Alternatively, the vehicle speed sensor 120 may be a sensor thatmeasures the relative velocity and/or acceleration of the vehicle, forexample an ultrasonic sensor or an infrared sensor that determines thespeed of the vehicle relative to another object. The other object may bea stationary portion of the road or a nearby vehicle. However, thevehicle speed sensor 120 may determine the speed of the vehicle 10 usingany other suitable method or sensor type.

The processor 130 functions to render content on the display 110 basedupon the operational mode of the display system 100: a first mode,wherein a first content is rendered on the display 110 at a first powerconsumption level, the first content including identificationinformation of the vehicle 10 and/or registration information of thevehicle 10; a second mode, wherein a second content is rendered on thedisplay 110, the second content including a message and possiblyincluding identification information of the vehicle 10 and/orregistration information of the vehicle 10; and a third mode, whereincontent is rendered on the display 110 at a second power consumptionlevel that is less than the first power consumption level. Preferably,content rendered in the third operational mode includes theidentification and registration information of the vehicle 10. In avariation of the display system 100, content rendered in the thirdoperational mode includes a message in addition to the identificationand/or registration information of the vehicle 10. However, contentrendered on the display 110 in the third operational mode may includeany other information or messages or any combination thereof.

The processor 130 is preferably coupled to the vehicle speed sensor 120.As mentioned above, the speed determined by the vehicle speed sensor 120may be the actual speed of the vehicle 10 or may alternatively be thespeed of the vehicle 10 relative to another object (for example, aneighboring vehicle). The processor 130 preferably selects theoperational mode of the display system 100 based on the speed and powerstate of the vehicle 10. However, a device other than the processor,such as the onboard computer of the vehicle 10, a law enforcementofficer, a second processor connected to a remote server, or any othersuitable device or institution may select the operational mode of thedisplay system 100. The processor 130 preferably operates the display110 in the first and second operational modes when the vehicle 10 is on,and the processor preferably operates the display 110 in the thirdoperational mode when the vehicle 10 is off. The vehicle 10 ispreferably considered “on” when the driver turns any portion of thevehicle 10 on. In many cars, there is a plurality of “on” states, forexample, a first “on” state in which basic functionality, such asopening and closing windows, is allowed; a second “on” state in whichmore advanced and/or higher-power functionality, such as ventilationsystems or the sound system, is allowed; and a third “on” state in whichthe vehicle may be driven. The vehicle 10 may be considered “off”otherwise. In the “off” state, certain portions of the vehicle may stillbe “on”, for example, security sensors, key proximity sensors (such askeyless entry), or any other type of substantially-low-powerfunctionality. Alternatively, in some embodiments the vehicle 10 may beconsidered “on” when the ignition is on and considered “off” when theignition is off, regardless of any other functionality that the vehiclemay provide to the driver. Yet alternatively, the vehicle 10 may beconsidered “on” when the presence of a person is detected within thevehicle and “off” when there is no one within the vehicle. The vehicle10 may also be considered off when the emergency brake or transmissionparking brake of the vehicle 10 is engaged, regardless of the state ofthe ignition or presence of a person within the vehicle 10. However, thevehicle may be considered “on” and “off” using any other suitablecriteria. The processor 130 preferably operates the display 110 in thefirst operational mode when the vehicle 10 is at a first speed andpreferably operates the display 110 in the second operational mode whenthe vehicle 10 is at a second speed lower than the first speed. Thesecond speed is preferably substantially zero speed, or substantiallyclose to zero speed. This allows for identification and/or registrationinformation of the vehicle 10 to be substantially visible while thevehicle 10 is in motion (the first speed), as shown in FIG. 1. Thisallows any party external to the vehicle 10 to visually access theinformation rendered on the display 110 in a manner similar to that usedto visually access information on a static (or stamped) license plate.In one variation, the processor 130 operates the display 110 in thesecond operational mode and renders the second content on the display110 when the vehicle 10 is on and at the second speed, wherein thesecond speed is preferably zero speed or a substantially slow speed,such as when the vehicle is moving slowly through heavy traffic. Becausethe message depicted in the second mode takes up a portion of thedisplay area of the display, the identification and/or registrationinformation also depicted may consume a smaller portion of the displayarea in the second operational mode as compared to the first operationalmode. Because the identification and registration information isdepicted in a is smaller size on the display 110 when a message isdisplayed concurrently with the vehicle 10 information, the visibilityof the identification and registration information may be less in thesecond operational mode than in the first operational mode.Alternatively, the identification and/or registration informationrendered on the display 110 in the second operational mode may be of thesame or similar format (for example, size and layout) as in the firstmode, but the message may be rendered on the display to overlap theidentification and/or registration information. This may also result inreduced visibility of the identification and/or registration informationof the vehicle 10. Therefore, the message may be displayed only undersuch conditions as when the vehicle is stopped or nearly stopped so thatdecreased visibility of the identification and/or registrationinformation does not occur when the vehicle 10 is moving at asubstantial speed; however, the additional functionality of displayingthe message when the vehicle is at the second speed still remains.Additionally, the message may provide an undesired distraction for aparty outside of the vehicle 10 while the vehicle 10 is in motion, andthus, by only displaying the message while the vehicle is stopped ornearly stopped, the possibility of distraction may be substantiallyreduced. However, the processor 130 may alternatively operate thedisplay 110 in the first and second operational modes at any othersuitable speed arrangement. In a variation of this, the display system100 may enhance legibility of the information for a party outside of thevehicle 10 by horizontally mirroring content rendered on the display 110when the display 110 is mounted on the front exterior of the vehicle 10;in this variation, content rendered on the display may be read in thecorrect orientation by a party viewing the display 110 in a rearview orside mirror of a second vehicle located ahead of the vehicle 10.However, the processor may render content on the display 110 by anyother means or arrangement such that distraction caused by the display110 is reduced and legibility of the displayed content is improved.

As described above, the processor 130 preferably functions to operatethe display 110 in the third operational mode when the vehicle 10 isoff. The third operational mode preferably displays identification andregistration information of the vehicle 10 at a second lower powerconsumption level that is less than the first power consumption level.In a variation of this, a message is rendered on the display 110 inaddition to the identification and registration information of thevehicle 10, although any one or combination of a message, identificationinformation of the vehicle 10, registration information of vehicle 10,or any other information may be rendered on the display 110 when in thethird operational mode. When the vehicle 10 is off, the power availableto the display system 100 may be less than when the vehicle is on. Forexample, in the variation wherein the display system 100 obtains powerfrom a power source of the vehicle 10, the display system 100 may beutilizing energy that was stored from another period of time when thevehicle was on. Thus, there is a limited supply of power, and byoperating the display 110 at a lower power consumption level in thethird operational mode than in the first and/or second operational modeswhile the vehicle is off, the length of time that content may berendered on the display 110 may be increased for a given amount ofenergy available to the display system 100.

The operation of the display 110 in the third operational mode mayreduce the power consumption of the display system 100 in a variety ofarrangements. In a first variation, the display 110 may be turned off ata first time and turned on at a second time. The display 110 may betimed to cycle on and off at specific time intervals, for example, everyfive minutes. The driver, the owner, or any other suitable party mayadjust the intervals. This allows the display 110 to be turned off for alength of time and turned on for another length of time. The length oftime that the display 110 is turned off is preferably substantiallylonger than the length of time that the display 110 is turned on, whichsubstantially decreases the power consumption of the display 110. In afurther variation, when in the third operational mode, content may berendered on the display 110 in colors that require less power todisplay, as compared to when operating in the first operational mode.However, the processor may operate the display 110 by any other meansthat reduces power consumption of the display 110 when in the thirdoperational mode, as compared to the first operational mode.Furthermore, the processor 130 may reduce the power consumption level ofthe processor 130 when in the third operational mode, for example, byreducing clock speed, shutting down auxiliary functions such astransmitting data to and/or receiving data from the communicationsdevice 140, or any other method to reduce power consumption of theprocessor 130. When the processor 130 operates the display in the thirdoperational mode, the light intensity of the display 110 may besubstantially identical to the light intensity of the first and/or thesecond operational modes. Alternatively, because the vehicle 10 ispresumed to be stationary when off (a possible exception to thispresumption would be when the vehicle 10 is being towed) and the partyto which message and/or identification information and/or registrationinformation is to be shown is substantially proximal to the vehicle 10,the light intensity of the display 110 may be substantially less in thethird operational mode than in the first and/or second operationalmodes. However, any other suitable light intensity may be used in thethird operational mode.

In a second variation, the display may be continuously on when operatingin the third operational mode but at a substantially lower lightintensity than in the first and/or second operational modes. In oneexample, the backlight of the display 110 may be at the lowest lightintensity in the third mode. The method and arrangement to decrease thepower consumption of the display 110 in the third operational mayalternatively be a combination of the above variations or any othersuitable method or arrangement, including use of bistable displays thatcan be externally illuminated, with illumination levels beingadjustable.

The processor 130 may alternatively operate the display 110 in a fourthoperational mode. The fourth mode may be determined by communicationthrough the communication device 140. In a first example, thecommunication device 140 may communicate with a law enforcement agencyand may indicate to the processor 130 that the vehicle 10 has beenstolen. The processor 130 may then operate the display 110 in a fourthoperational mode in which a notification that the vehicle 10 is a stolenvehicle is rendered on the display 110. However, the fourth mode mayalternatively be of any other suitable type and actuated by any othersuitable method.

The communication device 140 functions to allow content, information,and/or data to be transferred to and from the display system 100. Thecommunication may be conducted with an official organization (such as aDMV office or a law enforcement agency), a content database, the driverof the vehicle, the owner of the vehicle, or any other suitable party.The communication device may transmit and/or receive informationregarding vehicle identification and/or registration information,vehicle maintenance information, driver information, vehicle locationinformation (for example, in the variation of the display system 100that includes a GNSS or GPS location receiver or accesses GNSS/GPSlocation services), updated advertisements, or any other suitable typeof information. The communication device 140 is preferably of a wirelesscommunication type, for example, one that communicates with cellularphone towers, Wi-Fi hubs, or any other suitable type of wirelesscommunication. However, the communication device 140 may be a wiredcommunication device. In this variation, updated information istransferred when the display system 100 is “plugged in” to an updatingdevice, for example, a computer at a maintenance facility, at a DMVoffice, or any other suitable location, or another vehicle and/ordisplay system 100 that has wireless communication capabilities. Thecommunication device 140 may also include a communication processor thatfunctions to interpret communications to and/or from the display system100. The communication processor is preferably separate from theprocessor 130, but may alternatively be the processor 130. Thecommunication processor may function to encrypt and/or decryptcommunications to and/or from the display system 100. Theencryption/decryption may be any one of a variety of authentication andencryption schema. For example, cryptographic protocols such asDiffie-Hellman key exchange, Wireless Transport Layer Security (WTLS),or any other suitable type of protocol. The communication processor mayalso function to encrypt data to encryption standards such as the DataEncryption Standard (DES), Triple Data Encryption Standard (3-DES), orAdvanced Encryption Standard (AES). However, the communication device140 may allow any other suitable type of communication and may be of anyother suitable arrangement.

The communication device 140 may receive content, information, and/ordata from a content database. Preferably, the content database isarranged substantially remote from the processor 130. The contentdatabase also preferably contains content provided by an institution,for example, an advertiser, a school, a record company, or a sports teamor venue; content provided by the institution preferably includesadvertisements. Alternatively, the content database may contain contentprovided by the driver and/or owner of the vehicle 10, for example, amessage composed by the owner of the vehicle 10 congratulating a childupon graduation from high school. However, any other suitable party mayprovide content to the content database, and the content database mayinclude a combination of advertisements from one or more institutionsand personal messages from one or more individuals. In a first example,content on the content database is accessed by the processor 130 via thecommunication device 140 and stored on the storage device 150.Preferably, the storage device 150 is arranged substantially proximal tothe display 110, such as within the vehicle 10 or within a housingcontaining the display 110; however, the storage device 150 may belocated remotely from the vehicle 10, such as on a hard drive connectedto a remote server. In a second example, content on the content databaseis accessed via the communication device 140 in real time and thenrendered on the display 110, thereby bypassing storage of content on thestorage device 150. However, content from the remote message databasemay be accessed by any other means before being rendered on the display110. In a third example, the storage device also functions as thecontent database, wherein content from at least one institution orindividual, such as those listed above, may be stored on the storagedevice and also selected by the driver and/or owner of the of vehicle 10to be rendered on the display 110. In this variation, the storage device150 of the display system 100, also functioning as a content database,may be accessed by a second display system separate from the displaysystem 100, such as a display system arranged on a second vehicle.However, any other suitable party may select the content to be renderedon the display 110 from the content database. Furthermore, content onthe content database may be selected, accessed and/or modified by thedriver and/or owner of the vehicle 10, or any other suitable party, viaan interface. Preferably, the interface is internet-based and accessiblevia a web browser, for example, on a mobile smart phone or on acomputer. In a first example, the driver and/or owner of the vehicle 10may access interface with an internet-capable mobile phone, then loginto the content database and select content (for example, a SanFrancisco Giants Baseball banner) he wishes to be rendered on thedisplay 110. In a second example, the content database stores vehicleregistration information, and upon the renewal of the registration ofthe vehicle 10, a DMV representative may access the content database viaa computer equipped with the interface and then update the registrationinformation of the vehicle 10 on the content database; the communicationdevice 140 may then retrieve the updated registration information fromthe content database and the registration information subsequentlyrendered on the display 110 may reflect the renewal. Alternatively, theinterface may be a handheld device that is hardwired, or physically“plugged in”, to the display system 100. In this variation, theinterface may or may not be removable from the display system 100.Furthermore, the interface may not couple to the content database viathe communication device 140, but instead only provide the driver and/orowner of the vehicle 10, or any other suitable party, to access contentalready located on the display system 100, such as on the storage device150 arranged substantially proximal to the display 110. For example, alaw enforcement officer, upon pulling over the driver of the vehicle 10for a traffic violation, may hook up to the display system 100 arrangedon the vehicle 10 a device equipped with the interface, wherein theinterface provides access to the current identification and/orregistration information of the vehicle 10. However, the interface maypermit access to any content contained in any other device coupled tothe display system 110 and by any other means.

The communication device 140 may transmit data regarding the renderingof a particular content on the display 110. Preferably, an advertisementis included in the content rendered on the display 110, and thecommunication device 140 transmits data regarding the rendering of theadvertisement on the display 110. This data may include, for example,how long the advertisement was displayed, when it was displayed, andwhere it was displayed. Alternatively, this data could be collectedand/or stored by the processor 130, although it could be collected andstored by any other device or means. Preferably, this information isused to determine the magnitude or type of an award granted to thedriver and/or owner of the vehicle 10. In a first example, if anadvertisement for tickets to a baseball game featuring a given team isrendered on the display 110, the driver and/or owner of the vehicle 10may receive a monetary award commensurate with the length of time thatthe advertisement was rendered on the display 110; alternatively, theowner and/or driver of the vehicle 10 may receive one or more tickets toa baseball game featuring this team in return for displaying theadvertisement in an area with a relatively low attendance at baseballgames. However, any other method may be used to grant an award of anyother type to the driver and/or owner of the vehicle 10 in return forthe rendering of content on the display 110.

The sensor for determining the proximity of the vehicle 10 to a secondvehicle functions to indicate to the processor 120 to modify contentrendered on the display 110. The processor 120 preferably renders amessage, such as an advertisement, on the display 110 when the secondvehicle is substantially proximal to the vehicle 10 (such as in thesecond mode); the processor 120 preferably renders the identificationand registration information of the vehicle 10 on the display 110 whenthe sensor detects that no second vehicle is substantially proximal tothe vehicle 10 (such as in the first mode or the third mode). The sensormay be a RADAR detector, a LIDAR detector, an IRtransmitter-photoresistor pair, a camera, or any other suitable deviceconfigured to detect the proximity of the vehicle 10 to a secondvehicle. In the embodiment of the sensor that is a camera, the cameramay be configured to detect identification information of the secondvehicle (such as the license plate number of the second vehicle); thisinformation may be used to determine the owner of the second vehicle andobtain information relating to the owner of the second vehicle. Theprocessor 120 may then modify content rendered on the display 110 basedupon the demographic of the owner of the second vehicle, such as bydisplaying an advertisement for discount prescription medications if theowner of the second vehicle is determined to be at least sixty years ofage; by displaying an advertisement for a women's fashion store if theowner of the second vehicle is determined to be female; or by displayingdriver information if the second vehicle is determined to be owned by orused by a law enforcement agency. In this example, identificationinformation of the second vehicle may be transmitted to a database ofvehicle identification information, wherein the database returnsinformation about the owner of the second vehicle 10, such as age,ethnicity, or gender; the database may be maintained by an entity suchas a DMV or the American Automobile Association (AAA). In anotherembodiment, if the second vehicle is equipped with a digital licenseplate, information can be directly requested and transmitted back to thefirst vehicle's digital license plate 202. Alternatively, the camera maybe configured to determine directly the demographic of the driver of thesecond vehicle (for example, by matching the driver to a specificethnicity by with facial recognition software) or the response of thedriver of the second vehicle to a message rendered on the display 110.In the latter example, the response of the driver of the second vehiclemay be used to pick an alternative message that may produce a morefavorable response if the initial response is negative, or to choose asimilar message if the first response is positive. Furthermore, in theembodiment in which the sensor is a camera, the camera may be used tomeasure the level of ambient light substantially proximal to the vehicle10 such that content may be rendered on the display at an appropriatelight level; for example, the brightness of the display may increase ifthe camera determines a high level of sunlight near the vehicle 10.However, the sensor may detect any other information relevant to thesecond vehicle and indicate to the processor 120 to modify contentrendered on the display based upon any other variable.

FIG. 2 illustrates various systems, sub-systems, or modules that can beincorporated into a digital license plate system 200, along potentialinteracting agents such as vehicle systems 218, vehicle occupants, orthird party persons, vehicles, other digital license plates or externalautomated systems 220. In this Figure, a digital license plate 202 canbe mounted on a vehicle. Systems within the digital license plate caninclude, but are not limited to, a power system 204, thermal controlsystem 206, and sensor system 208. An electronic security system 210limits unauthorized access to data logged and distributed via a datalogging and interface system 212, or any received/transmittedcommunications through communication system 214. Received data can beused to determine or update information presented by display 216.FIG. 3illustrates a method for operation of one embodiment of a digitallicense plate system. After an initial setup 302 to register and link adigital license plate to a specific vehicle, the digital license platecan be ready for initialization 304 on vehicle startup (oralternatively, on vehicle stop), and can use timers or sensors to helpidentify context, location, or display presets for the digital licenseplate. Data uploading/downloading can be initiated, and anyfirmware/software updates completed. In normal operation, changes 306 tothe display can occur in response to sensed data 308, from data storageor analysis system 310, or as a result of external communication anddata transfer 312. Similarly, sensed or stored data can be transmittedor received, and the sensors activated, deactivated, or sensor dataanalyzed based on internal triggers or externally received data. When avehicle stops, or in response to a timing or other suitable trigger,data can be transferred (via line 314) back to the initialization step304. FIG. 4 illustrates a representative data transfer and storagesystem 400 including both vehicle mounted and externalapparatus/software for interacting with a digital license plate such asdiscussed herein. As shown in FIG. 4, a preferred digital license platesystem 400 for rendering content on a vehicle includes a display 410, amemory 420, a communication module 430, and a processor 440. The display410 is configured to mount adjacent an exterior surface of a vehicle.The memory 420 is configured to store a plurality of executableapplications including a vehicle identification application and anapplication elected by a user. The communication module 430 isconfigured to download the user-elected application to the memory 420.The processor 440 is configured to selectively execute applications tocontrol visual content rendered on the display 410, wherein the display410 renders vehicle identification information when the vehicleidentification application executes, and wherein the display 410 rendersadditional visual content when the user-elected application executes.

The digital license plate system 400 preferably functions to execute aplurality of applications, wherein the display 410 renders visualcontent specific to each application for viewing from outside a vehicle.When executing a vehicle identification application, the preferredsystem 400 preferably functions as a digital license plate by displayinga government-issued license plate number of the vehicle. However, whenexecuting another (i.e. a user-elected) application, the preferredsystem 400 preferably functions as a toll payment, interstate trucking,messaging, advertising, gaming, news, alert, or other application bydisplaying visual content relevant or specific to the user-electedapplication. The vehicle identification application is preferably adefault and/or preloaded application executable on the system 400, andadditional applications are preferably elected by the user. Theadditional or user-elected applications are preferably downloaded from aremote server containing a plurality of available applicationsexecutable on the system 400 such that the user can customize the system400 to perform certain functions and/or to display certain visualcontent, types of visual content, forms of visual content, etc. Thepreferred system 400 can then switch between displaying vehicleidentification information and displaying additional visual content,types of visual content, forms of visual content, etc. specific to theuser-elected application. The user can therefore select variousapplications from a set of available applications to enable certainfunctionalities of the system 100.

The memory 420 of the system 400 is configured to store executableapplications, including the vehicle identification application and theapplication elected by the user. The memory 420 can preferably storeadditional user-elected applications, application-specific orapplication-related data (e.g., vehicle identification information, tollpayment information, a user-defined personal message), user preferences(e.g., fonts, visual content types, power settings), or any otherrelevant information pertaining to the operation of the preferred system400. In one variation of the preferred system 400, the memory 420 ispreloaded with the vehicle identification application and vehicleidentification information (e.g., a license plate number) that is uniqueto the vehicle and/or to the system 400. In this variation, the vehicleidentification information is preferably unalterable.

The memory 420 is preferably in communication with the processor 440such that the processor 440 can access application data and visualcontent from the memory 420, execute the application, and push visualcontent from the memory 420 to the display 410 for rendering. The memory420 is preferably physically coupled to the processor 440 and arrangedwithin a housing shared with the display 410 and the processor 440.Alternatively, the memory 420 can be arranged within the vehicle andremote from the display 410, such as adjacent or physically coextensivewith an electronic control module (ECM) integrated into the vehicle. Thememory 420 can alternatively be a remote memory coupled to a remoteserver, wherein the processor 440 accesses the remote memory via thecommunication module 430 in communication with the remote server. Thememory 420 can alternatively be physically coextensive with memoryincorporated into a mobile electronic device carried by the user, suchas a smartphone or tablet. However, the memory 420 can be arranged inany other way relative to the display 410, and the memory 420 can beaccessed over a wire, via wireless communication (e.g., Wi-Fi, cellular,Bluetooth, RFID), and/or through the communication module 430 in anyother way or according to any other protocol.

The communication module 430 preferably accesses a remote server thatstores a plurality of applications, wherein each application on theremote server can be selected by the user and subsequently downloadedto, uploaded to, installed on, or executed on the preferred system 400to enable a particular function defined by each application, as shown inFIG. 2. In one variation of the preferred system 400, the remote serverfunctions as an application store through which the user can access orbuy applications, wherein the processor 440 accesses the remote serverthrough the communication module 430 to download an application selectedby the user. In this variation, personal user information and/or vehicleidentification information is preferably used to automatically bill theuser, a fleet manager, or any other entity associated with the vehiclefor the purchase of the elected application. In one variation, thecommunication module 430 communicates directly with a remote server viaa wireless communication protocol. In an example implementation, thecommunication module 430 communicates with the remote server over acellular (e.g., 4G cellular) network and downloads the user-electedapplication over the cellular network. However, the communication module430 can wirelessly communicate substantially directly with the remoteserver, such over Wi-Fi and a local area network connection, Bluetooth,satellite, or any other suitable type of short- or long-range wirelesscommunication protocol. In another variation of the system 400, thecommunication module 430 communicates with the remote server through awireless-enabled mobile device. In one example implementation, thecommunication module 430 includes a port configured to accept a physicalwire connectable to a smartphone carried by the user, wherein thesmartphone wirelessly accesses and pulls information from the remoteserver and subsequently uploads the information via the wiredconnection. In another example implementation, the communication module430 communicates with a tablet computer over short-range wirelesscommunication protocol (e.g., Wi-Fi, Bluetooth, RFID, near fieldcommunication (NFC), infrared), wherein the tablet computer communicateswith the remote server via long-range wireless communication protocol(e.g., cellular, satellite) to transfer information from the remoteserver to the communication module 430. In these exampleimplementations, the communication module 430 preferably receivesapplication-related data from the mobile electronic device substantiallyin real time. Alternatively, the communication module 430 can receiveapplication-related data substantially long after the mobile electronicdevice accesses and stores the application-related data locally.However, the communication module 430 can access and downloaduser-elected application data and related visual content via any othercommunication protocol, through any other secondary or mobile electronicdevice, or in any other way.

The communication module 430 is preferably configured to receive datafrom the remote server, including the user-elected application,application-related data, and additional visual content. However, thecommunication module 430 can also transmit data to the remote server,such as vehicle location data, visual content exposure (e.g., how longvisual content is rendered on the display 410, how many individuals reador noticed the visual content), a user preference, vehicle or vehicleoccupant identification information, a local person, vehicle, orenvironmental condition, or any other relevant data or information. Suchdata is preferably stored on the memory 420 and transmitted to theremote server when a suitable connection is established (e.g., through aWi-Fi-enabled mobile electronic device or according to a predefinedsystem update schedule. However, the memory 420 can store any other dataand the communication module 430 can send and/or receive any otherrelevant information to and/or from the remote server.

The processor 440 of the system 400 is configured to selectively executeapplications to control content rendered on the display 400, includingthe user-elected application and the vehicle identification application.The processor 440 is preferably arranged within the housing that alsocontains the memory 420 and the display 400, though the processor 440can alternatively be remote from the display 400, such as arrangedadjacent or physically coextensive with an ECM of the vehicle. Theprocessor 440 is preferably coupled to memory and to the display 410 viaa wired connection, such as a trace on a shared printed circuit board(PCB). However, the processor 440 can alternatively communicate with thememory 420 and/or display via a wireless or optical connection.Furthermore, the processor 440 can be physically coextensive with aprocessor of a mobile electronic device carried by the user. However,the processor 440 can be arranged in any other way, and the processor440 can communicate with the memory 420 and/or display in any other wayor according to any other protocol.

The processor 440 preferably handles transitions between applicationsand controls physical content rendered on the display 410. Byselectively executing applications, the processor 440 can execute thevehicle identification application exclusively, the user-electedapplication exclusively, and/or the vehicle identification applicationand the user-elected application simultaneously. When executing thevehicle identification application, the processor 440 preferablyaccesses vehicle identification information stored on the memory 420 andhandles rendering the vehicle identification information on the display410. The processor 440 also preferably accesses necessary applicationand application-related data from the memory 420 when executing theuser-elected application. The processor 440 can additionally oralternatively access relevant data directly from the remote server, suchas via the communication module 430, to execute the application andselect content to render on the display 410. The processor 440preferably selectively executes the applications based upon the locationof the vehicle, the proximity of the vehicle to a known or identifiedentity, an input from the user, an input from a known or identifiedentity outside of the vehicle, a user preference, a timer, a quality ofa second local vehicle (e.g., child occupancy, a demographic of adriver, a driving record of a driver, the make and model of the secondvehicle), or any other suitable trigger or input. A transition betweentwo applications can be native to one or more applications, defined bythe processor 440 outside of an application, set by the remote server,triggered by the user, or triggered by a second user or other entityoutside of the vehicle. However, the transition between applications canbe generated, defined, or set in any other way or by any other party.

In a variation of the system 400 in which a transition betweenapplications is triggered by a party external the system 400 (e.g., theuser, a second user, an external entity), the processor 440 preferablyreceives the trigger event through the communication module 430. In oneexample implementation, the communication module 430 includes a GNSS/GPSsensor, and the processor 440 transitions to a toll application when thecommunicate module estimates that the vehicle is within a specifiedrange of a tollbooth. In another example implementation, thecommunication module 430 includes an infrared (IR) sensor, and theprocessor 440 transitions to the vehicle identification application whena police officer points an IR remote at the communication module 430. Inyet another example implementation, the communication module 430includes an input region (e.g., a physical switch, a touch screen)arranged within the cabin of the vehicle and accessible by the user, andthe processor 440 transitions between applications based upon a userinteraction with the input region (e.g., flipping the switch, selectinga touch screen input region). However, the trigger can be any other typeof input provided or generated by any suitable user, individual, orentity.

In one variation of the system 400, the processor 440 executes thevehicle identification application that prompts the display 410 torender government-issued vehicle identification information. The display410 preferably renders a government-issued license plate number when theprocessor 440 executes the vehicle identification application, thoughthe display 410 can depict additional identification information, suchas registration information, the name, permit, or driver's licensenumber of a current occupant or driver, the license-issuing state, or adriving record of the current driver or owner of the vehicle. Thelicense plate number or other identifier of the vehicle is preferablystored on a non-volatile, read-only portion of the memory 420 such thatlicense plate number or other identifier cannot be changed onceprogrammed onto the system 400. Alternatively, the license plate numberor other identifier can be protected by one or more firewalls,passwords, secure embedded systems (OS kernel, CPU, memory), passwords,cryptography schemes, etc. to substantially prevent illegal tamperingwith government-issued registration and identification informationloaded onto the system 400 that is mounted or otherwise coupled to thevehicle.

In this variation, the vehicle identification application can benational-, state-, or local government-specific such that variousgovernment entities can issue customized vehicle identificationapplications tailored to the rules, regulations, registrationprocedures, needs, etc. of each national, state, or local government. Inone example, states can set different font sizes or typefaces, defineplacement of license plate numbers and registration tags, providespecial templates or designs, or define any other formatting orstylistic property of visual content rendered on the display 410 throughthe vehicle identification application. In another example, stategovernments can set automatic registration protocols, such as howregistration requests are routed to a department of motor vehiclesserver and how a digital registration “sticker” is transmitted back tothe system 400 as a vehicle identification information update. In afurther example, local governments can set how or when vehicleidentification information is installed on the system 400, such asduring manufacture or assembly of the system 400, when the system 400 isinstalled on a vehicle following delivery to a dealer, when the vehicleincluding the system 400 is first registered at a DMV, when the vehicleincluding the system 400 changes hands, and/or when an owner or userrequests a license plate template change (e.g., standard to historicvehicle plate) or a change to vehicle registration (e.g., operational tonon-op status, passenger to commercial vehicle status). In still anotherexample, state governments can set triggers controlling transitions intothe vehicle identification application, such as when the vehicle iswithin a preset range of an intersection, when the vehicle is within apreset range of a police officer, at specified intervals, when thevehicle is moving above a certain speed, when the vehicle is parked,when the vehicle is in a certain location, or given a trigger from astate-issued remote control device. However, national, state, and/orlocal governments can set any other relevant parameters of the vehicleidentification application and/or the vehicle identification informationrendered on the display 410 when the vehicle identification applicationexecutes. These parameters can also be modified or redefined over time,such as with updates for the vehicle identification applicationdistributed to the system 400 via the remote server.

In one variation of the system 400, the user-elected application is anadvertising application, wherein the display 410 renders the additionalvisual content that is an advertisement when the advertising applicationexecutes. In this variation, the user can select specific advertisementsto render on the display 410. For example, the user who is a Giantsbaseball fan can select advertisements for tickets to Giants baseballgames. In another example, the user that is a car dealership can selectvehicle discounts and other dealership advertisements to be rendered onthe display 410 when the vehicle is parked in a dealer lot. Additionallyor alternatively, the user can elect certain advertising preferences orprovide personal or demographic information that control whichadvertisements are rendered on the display 410. In one example, for theuser who is a vegan, advertisements for fast food meat products areexcluded from the advertising application executing on the system 400mounted to the vehicle owner by the user. In another example, whitewaterrafting trips are rendered on the display 410 for the user who enjoysoutdoor activities. In yet another example, for the user who is acountry music fan, a playlist for a local country music radio station isrendered on the display 410. In this variation of the system 400, theadditional visual content is preferably targeted at a second user,individual, etc. outside of the vehicle. The second user, individual,etc. outside of the vehicle is also preferably within a field of view ofthe display 410 such that the advertisement is legible for the seconduser, individual, etc.

In this variation, the processor 440 can track advertisement exposuresuch that the user can be compensated for advertising products, goods,or services on the vehicle. In one example, the processor 440 tracks theamount of time an advertisement is displayed. In another example, theprocessor 440 is coupled to a camera and implements machine vision toidentify and count the number of individuals who looked at display whilethe advertisement is rendered. In a further example, the system 400implements global positioning to track the number of vehicles within afield of view of the display 410 while the advertisement is rendered. Inthis variation, the display 410 time or amount of exposure of theadvertisement is preferably used to calculate the amount of usercompensation for the advertisement. Distribution of funds, prizes,discounts, coupons, or other forms of compensation are preferablyhandled by the remote server that accesses an account of the user, fleetmanager, vehicle owner, etc. to deposit the compensation to the user orother suitable entity.

In another variation of the system 400, the user-elected application isa road alert application, wherein the display 410 renders a road alertwhen the road alert application executes. In this variation, the display410 preferably renders content substantially relevant to a second useroutside of the vehicle, such as a second user who is following thevehicle in a second vehicle. The road alert application preferablyinforms the second user of upcoming road hazards, such as trafficconditions, accidents, potholes, construction, narrowed lanes, changesto a carpool lane or carpool lane restriction, onramps, or debris.Notification of tailgating, erratic driving, or dangerous behavior canalso be provided to following vehicles. In one example implementation,the user elects the road alert application in order to inform trailingvehicles of upcoming traffic or road conditions, which can improvedriving safety of the user by improving current traffic-relatedknowledge of other drivers around the user. In another exampleimplementation, the second user, who is following the vehicle in asecond vehicle, requests installation of the road alert application onthe system 400 coupled to the vehicle. In this example implementation,the remote server preferably identifies the second user and/or thesecond vehicle that is/are proximal the user and/or the vehicle, such asthrough GNSS/GPS tracking or short-range communications. The remoteserver then preferably checks the application request againstpreferences of the user and uploads the road alert application to thesystem 400 when appropriate. Similarly, in an example implementation inwhich the road alert application is already installed on the system 400,the second user can supply an input (e.g., via a smartphone) to triggera transition into the road alert application or to select particularroad-related information to render on the display 410, such as ‘trafficconditions for the next five miles.’ Therefore, individuals or entitiesoutside of the vehicle can substantially control an applicationinstalled on the system 400, a transition between two applications,and/or a selection of additional visual content rendered on the display410 when the processor 440 executes the application.

In another variation of the system 400, the user-elected application isa driving direction application, wherein the display 410 renders adriving direction when the driving direction application executes. Thedriving direction application is preferably similar to the road alertapplication described above, wherein the system 400 displays informationrelevant to an individual outside of the vehicle. In this variation, thedisplay 410 preferably depicts a driving direction for a second userdriving behind the vehicle and within a field of view of the display 410such that the second user does not need to remove his eyes from the roadto view a driving direction. As described above, installation of thedriving direction can be initiated by the user or requested by thesecond user. The second user also preferably requests directions to adestination, wherein the directions are handled by a remote server andpushed to the system 400 for presentation to the second user. The system400 and/or the remote server can also identify additional vehiclesproximal the second user and distribute driving directions acrossmultiple vehicles followed by the second user over the course of thetrip. However, the system 400 can implement the user-elected applicationthat is a driving direction application in any other suitable way.

In another variation of the system 400, the user-elected application isa news application, wherein the display 410 renders a news alert whenthe news application executes. In this variation, the display 410preferably renders local, state, national, or international currentevents, such as national political headlines or international economicheadlines. Additionally or alternatively, the display 410 can renderpersonal news or events related to the user or other individualsproximal the user, such as a news feeds, status update, message, or postsourced from a social network, blog, or other online service or network.For example, the display 410 can render a user status update that is “Soexcited—I just bought tickets for the Giants game tomorrow night,” or“my friend Sammie just posted a new chili recipe to her cooking blog.”In this variation, the display 410 can also render a visual pointerlinking to the source of news content. For example, the display 410 canrender a two-dimensional bar code, wherein an individual outside of thevehicle can user a smartphone implementing a camera to read the bar codeand automatically access a news article, social network, blog, etc. fromwhich the news content was sourced. Similarly, the communication module430 can (wirelessly) output the pointer that is then accessed by amobile electronic device carried by an individual outside of the vehicleto open the source of the news content.

In another variation of the system 400, the user-elected application isan interstate trucking application, wherein the display 410 exhibits thestatus of trucking certifications for the vehicle that is a commercialtruck traveling across a state border. In this variation, the system 400preferably interfaces with a local or global positioning system to trackthe location of the vehicle, such as when the vehicle crosses a stateborder and/or which roads the vehicle has covered. From this vehiclelocation information, the system 400 and the remote server preferablycooperate to pay required fees and taxes, submit required vehicleinformation (e.g., vehicle gross weight) to relevant authorities (e.g.,a department of motor vehicles), and to render visually on the display410 the current status of vehicle certifications and payments. Forexample, an RFID tag included in the communication module 430 cantrigger an RFID reader proximal a highway near a state border, whereinthe trigger informs the remote server that the vehicle has crossed astate border, and wherein the remote server subsequently pushes relevantvehicle and payment information to an appropriate authority and thedisplay 410 renders visual indicators of the certifications and payment.In this variation, the trucking application is preferably installed onthe system 400 by the user who is a fleet manager for a vehicle fleetincluding the vehicle such that the fleet manager can use the truckingapplication executing on a plurality of vehicles in the vehicle fleet totrack and manage interstate trucking fees, payments, and certifications.However, in this variation, the trucking application can handle truckingcertifications to the exclusion of application-specific orapplication-relevant visual content, wherein the system 400 does notupdate visual content rendered on the display 410 when the processor 440executes the trucking application. However, the system 400 can functionin any other way when executing the user-elected application that is atrucking application.

In another variation of the system 400, the user-elected application isa messaging application, wherein the display 410 renders a personalmessage when the messaging application executes. In this variation, theuser preferably generates the personal message, and the message ispreferably text-based, though the message can additionally oralternatively include a static image or video. The user can generate themessage on a message generation website accessible on a computer andsupported by the remote server, through a message generation applicationexecuting on a mobile electronic device carried by the user andsupported by the remote server, through an onboard vehicle voice controlsystem coupled to the system 400, or through any other suitable means.For example, the user can generate the message that is “Happy 17thBirthday, Tom,” “Go Giants,” or “Acme Moving Services—call800.555.9876.” Alternatively, the user can select the message from apredefined set of messages or download the message from a website,online user profile, social network, etc. For example, the user candownload a “How's my driving? sign,” a “Baby on Board” sign, a digitalbumper sticker, or a background image for the display 410. Similarly,the user can pull the message from a social network post, comment, ormessage. However, the user can generate or select any other messageincluding any other content for rendering on the display 410.

In another variation of the system 400, the user-elected application isa tollway application, wherein the system 400 handles toll payments forthe vehicle passing through a tollbooth or toll plaza. Like theinterstate trucking application described above, the system 400executing the tollway application preferably monitors the location ofthe vehicle and/or communicates with a tollbooth or tollway to trigger atoll payment. The system 400 and/or remote server preferablyinterface(s) with the tollbooth or a toll management server to pay forthe vehicle toll, and once the toll has been paid, the display 410preferably renders visual content that indicates that the toll is paid.However, the tollway application can handle toll payments to theexclusion of visual content, wherein the system 400 does not change orupdate visual content rendered on the display 410 when the tollwayapplication executes. However, the tollway application can function inany other way.

In another variation of the system 400, the user-elected application isa gaming application, wherein the display 410 renders gaming contentwhen the gaming application executes. In this variation, the system 400preferably enables gaming between the user and any other individualproximal the user. For example, the user in the vehicle can play a gamewith a second user in a second vehicle when the second vehicle isfollowing the first vehicle, the user is facing a system 400 installedon the front of the second vehicle, and the second user is facing thesystem 400 installed on the back of the vehicle. In this example, theuser can control the output of a second display on the second vehiclevia a handheld electronic device, and the second user can control theoutput of the display 410 on the vehicle through a second handheldelectronic device. Therefore, the system 400, installed on a pluralityof vehicles, can enable a gaming platform or gaming interface for usersoccupying different but nearby vehicles.

The applications configured to execute on the system 400 are preferablycreated by third-party developers and hosted on the remote server suchthat the user can preview applications, select relevant applications,and install the relevant applications on the system 400 for subsequentuse. The remote server preferably provides a software development kit(SDK) and/or hosts an application programming interface (API) to supportapplication creation and development by the third-party developers. Thethird-party developers can represent government agencies (e.g., a stateDMV), private institutions (e.g., a private toll plaza on a privatehighway, a retailer), or independent users. However, the system 400and/or remote server can function in any other way to supportdevelopment of applications that enable additional functionalities forthe system 400.

FIG. 5 schematically illustrates a data system 500 including varioustypes or categories of data that is storable, analyzable, transmittable,or receivable by a digital license plate 502. Data can include vehiclegenerated data 504 that can be stored, directly sensed, derived, orcalculated from vehicle sensors or data sources, and can further includesensors provided in the digital license plate 502 and any supportingelectronics such as described in the disclosed embodiments. Other datacategories can include vehicle associated data 506 (e.g. licenseinformation, registration, expiration date, insurance status, vehiclemanuals, vehicle guides, or how-to information), third party data 508(e.g. advertiser information, road tour guides, games, entertainment),or simulation or analysis data created by a data analysis module 510(e.g. calculated tire or engine wear).

Data from digital license plate 502 can be provided to a user asinformation 512, typically via a smartphone application, text or emailmessages, vehicle dashboard screen, other, in-vehicle user interfaces,or web based interfaces (both in-vehicle or through a user's personalcomputer or laptop). Visual displays, printed information, audio, or anysuitable user interface can be used to provide the information.Information can be provided in response to a query, as a warningannouncement, or as a regular report. Information can be prioritizedaccording to time or importance, with learning algorithms able to adjusta presentation to provide information in a form best suited for a user.For example, over time, items commonly requested by a user, or keyperformance indicators/warnings can be presented on a main screen ratherthan requiring menu selection or navigation to sub-screens.

User data 514 can include personal data, as well as user feedback 516 inresponse to information 512, or various commands, instructions, orauthorizations 518 to allow access to or release of data from thedigital license plate 502. Preset security levels can be set andauthorized by a user, with modifications or changes being allowed. Forexample, a user might wish to invoke a privacy mode that preventsstorage or release of vehicle location history or vehicle speed. Inanother example, data relevant to advertisers can be authorized forrelease in return for access to a third party web site, use of asmartphone application, or payment.

Vehicle generated data 504 can include but is not limited to thatrelated to health of vehicle, display time and location of third partyadvertising images, gas mileage, road conditions (e.g. rough vs. smoothas detected by accelerometers), pothole identification, weatherconditions, temperature, humidity, number of people riding in vehicle,amount of weight placed in the vehicle, braking habits,acceleration/deceleration habits, and location and timing information tosupport usage based insurance. Other data useful for monitoring adigital license plate can include digital license plate operationalstatus, digital license plate battery status, camera readiness, memoryusage, external battery (i.e. vehicle battery) charge availability,voltage levels, and self-test/monitoring results.

Other vehicle generated data can include information related tomaintenance, including predictive maintenance based on data analysis 510(e.g. “Please take me in for service soon, transmission is predicted tofail within the next month.”). Expected maintenance costs can beprovided, as well as information relating to maintenance history, andrepaired or replaced parts.

Vehicle generated data can be combined with third party data 508,including that from vehicle conveyed electronic devices (e.g. personalsmartphones or cameras), or third party insurance or vehicle databasesto provide a wide range of information. This can include vehicle cost ofownership, readiness to purchase next vehicle: number of days since lastpurchase, mileage, gas usage and payment verification, cost comparisonwith last vehicle, cost comparison with a comparable third partyvehicle, or cost comparison with a similar fleet vehicle. Financialinformation related to the vehicle such as percentage paid off onvehicle, days until paid off, or verification of insurance payments canalso be provided.

Information (data with context) is presented to the customer, allowingthem to generate their own insights. For example, weekend vehicle usageand costs can be compared and separated from weekday business usage,allowing a user to determine cost of recreational use of a vehicle orhelp reduce overall vehicle costs. Suggestions or recommendations can bemade, for example, when and where to refill fuel (e.g. best resultsbeing on the weekend, at a low-cost gasoline station located in adirection opposite to a user's workplace, but near a restaurantwell-liked by the user). Such information and “insights” (i.e. databased suggestions or recommendations) can be communicated simultaneouslyto the user, who can be further prompted for actions such as remindersto visit the restaurant and fill up with fuel on the trip home.

Alternatively, list of insights requiring action can be presented to thecustomer. Continuing the foregoing example, a prioritized list of nearbygasoline stations can be provided, along with recommended times torefill. For example, the digital license plate 502 can integrate data504 (historical gas mileage), data 506 (recommended grade of vehiclegas), data 508 (location and reviews of gas stations), data 510(calculated or simulated vehicle location) and user data 514 (usercalendar provides available time and likelihood of visiting therestaurant based on recorded user habits) to provide a list ofrecommendations and resulting cost savings.

In another described embodiment, a digital license plate can directly orindirectly communicate with local entities capable of providing goods orservices. For example, in one embodiment, a Bluetooth communicationsystem on-board or connected to a digital license can communicate with aBluetooth compatible beacon or communication system at a servicesstation. As an example, fuel can be ordered and paid for, goods such asfood and drink can be purchased, and local information requested by adigital license plate interacting with a service station. In operation,once a vehicle with a digital license plate stops moving (e.g. aftermaneuvering to to stop in front of the gas pump), it can activate andattempt to read nearby Bluetooth packets and associated signal strength.Signal strengths and Bluetooth packet are recorded and sent to asoftware purchase system. The software purchase system will identify theuser, gas station and pump number. If signal strength is strong enoughto determine a pump with a defined accuracy, a message will appear onthe plate saying “Authorized! Please begin fueling from pump X.” If theplatform is unable to identify the pump the phone/plate will display“Please Move Vehicle Closer To Pump”. After conclusion of refueling, thepump indicates completion of transaction and provides a digital receipt(or paper receipt at the pump, if requested). In effect, digital licenseplate mediated payment for fuel is possible using only informationrelevant to a gas station as determined using on board GNSS/GPS from thedigital license plate; customer information as provided by the digitallicense plate database during setup; and fuel pump number, as determinedusing a set of pump associated beacons that transmit information to thedigital license plate.

As seen in FIG. 6, in certain embodiments a visual information transfersystem 600 includes a vehicle 601 having at least one attachable digitallicense plate 602 and optional digital license plate camera 612 that canpresent various visual codes suitable for enabling or simplifying datainteractions. These interactions can include but are not limited toproviding information to a user or other person, providing informationfrom a user to interact with the digital license plate, or provide amechanism for operating, facilitating transactions, or enabling servicesthat can be related to a vehicle or the digital license plate.

Information represented by these visual codes can be derived fromvehicle generated data 604, vehicle associated data 606, third partydata 608, or advertising data 610. For example, vehicle generated datacould include mileage information or information for service providersrelating to oil level, type, and time since last oil change. Vehicleassociated data 606 could include a vehicle identification number (VIN)or owner address. Third party data 608 could include symbolic indicatorsthat a parking fee has been paid to a third party, with a visuallyinspectable parking receipt being provided to the digital license plateby the third party. In other embodiments, a user or third party canprovide advertising data 610 accessible via a visual code.

These visual codes can be, alone or in combination, text, symbols,colors, or electronically readable codes such as barcodes. Text can berendered in font types that are easily recognized by electronic systems,and patterns or symbols can be high contrast and distinctive. Colors canbe selected from a limited palette with widely separated color types toreduce risk of mistaking color in low or poor light conditions (e.g. atnight, under sodium vapor lights). Barcodes can be numeric only (e.g.Interleaved 2 of 5, UPC-A, or UPC-E), alphanumeric (e.g. Code 128, Code39, or US Government LOGMARS code), or 2-Dimensional (e.g. PDF417,Datamatrix, or QR code).

As previously discussed with respect to FIG. 4, since the digitallicense plate 602 can render a two-dimensional bar or QR code, anindividual outside of the vehicle equipped with a smartphone having acamera can capture or read the bar code. This enables simplified accessto data such as a news article, social network, blog, etc. from whichthe content was sourced. Other applications can include those related tovehicle operation or service, including but not limited to of vehiclestart, vehicle stop, vehicle trunk open, vehicle gas cap release, dooropen, door close, vehicle hood open, and trunk open. For example, avehicle can be left at a facility for oil change or cleaning service.Scanning the visual codes with a smartphone returns authorizationinformation necessary to open the vehicle hood or car doors for service.This can even include limited authorization to start and move thevehicle within a restricted geographic area. Once service is complete,hoods or doors can be locked, and the vehicle owner remotely notifiedthat the vehicle is ready for pickup.

In those embodiments of the visual information transfer system 600supporting a digital license plate 602 having digital license platecamera 612, visual information (from visual information transfer module620) can be transferred to the digital license plate 602. For example, asmartphone could initiate a two-way exchange of visual information withthe camera equipped digital license plate. The digital license plate canread, for example, a QR code presented by the camera and initiateoperations such as door opening. Alternatively, if wirelesscommunication is not available, two-way transfer of substantial amountsof electronic information is still possible using bar codes or otherinformation.

FIG. 7 illustrates one embodiment of a digital license plate system 700including a digital license plate 702 supporting a camera 712. As seenin FIG. 7, a two-dimensional (QR) bar code 722 is displayed, along witha standard one-dimensional bar code 724, and a textual hyperlink 726presented in a font easily read by electronic devices such assmartphones. Various types of information can be presented, includinghyperlinks (722, 724, 726) or parking permits (QR code 730 and text 732.This information is typically displayed only when a car is parked, inresponse to an electronic request, or when certain conditions such asdetected location in a parking facility are true.

In certain embodiments, visual information can be remotely updated. Inother embodiments, the information can be presented in response to arequest. In still other embodiments, visual information between a cameraequipped smartphone and a digital license plate can be interactive. Forexample, a smartphone can visually present (to a digital license plateequipped with a camera) a QR code requesting certain information. Thedigital license plate can receive and interpret the request, and ifauthorized, render a suitable response in text or as a bar code. Sincethis visual request/provide procedure can be continued, the system cansupport visual transfer of information without requiring a wirelessconnection. This can be advantageous, for example, in an environmentwith large numbers of digital license plates, or localities with extremeelectromagnetic interference.

FIG. 8 illustrates vehicle rental assisted by digital license platepresented information. In this scenario, in step 802 a user wishing torent a vehicle without requiring assistance from a rental firmrepresentative, enters a lot containing vehicles having digital licenseplates displaying vehicle related identifying information. Once the useridentifies a suitable vehicle, the user can read the information using asmartphone equipped with a camera. In step 804, the smartphone remotelycommunicates with a server or cloud based system to transfer vehicleidentification any rental payment authorization. In return, in step 806the user receives smartphone authorization from the remote system. Thisinformation can be communicated wirelessly to the digital license platein step 808 to operate the vehicle. In those embodiments in which thedigital license plate is equipped with a camera, operation can beinitiated by visual information. Operation can include, for example,opening a door to allow access to a key or electronic key fob, orauthorization to allow vehicle start using a smartphone. When a vehicleis returned in step 810, the digital license plate can transfer mileageand fuel data to the smartphone for finalizing payment, and the displayreinitializes to present information indicating identity andavailability for rental.
